Machine the difference.
Up to the 1990ies we operated our own Graebener® pipe mill and prepared the weld seams of our pipes in a tedious manual process. Then, we developed the Graebener® seam milling machine – and today, more than 100 customers on four continents already benefit from our market leading machine technology.
Graebener® circ seam milling machines ensure the cost-efficient, reliable and safe preparation of circ seams at pipes, vessels and apparatuses. For this reason, they have been among the most popular seam milling machines for the preparation of seams of extremely narrow welding gaps for years. Actual usability studies give proof of cost benefits of more than 50 percent.
Your Graebener® machine will save you time and money since the circ seam milling machine is also suitable for a quick and reliable seam repair. Benefit from our individual concepts and numerous advantages in comparison to conventional gouging or grinding methods.
Graebener® circ seam milling machines are available in three different versions: as a transportable solution that can be easily positioned by crane or forklift to the workpiece, with an additional base for transportation by SPMT (self-propelled modular transporter) or as a rail-mounted solution.
In addition, the transportable milling machines can be positioned at different heights to the pipe sections using our special height adapter, allowing you to process very different diameters with one machine.
Based on various capacity classes we will find the optimum solution for a cost-efficient weld seam preparation. As custom machine builder we also develop customized special machine designs on request.
All Graebener® circ seam milling machines are equipped with an intelligent sensor system for the compensation of a possible unevenness or ovality. This way, your Graebener® machine ensures a constant depth of the seam preparation at any time.
Benefit from the technical advantages of your Graebener® circ seam milling machine:
Compared to the common processes such as carbon rod gouging or grinding, the Graebener® milling process provides numerous advantages:
As operator you can save time and money as proven by real case studies at our customers. You also preserve the health of your operators and considerably improve the quality of the seam preparation – eliminating the need for manual reworking.
